A TTOH/VEY UNITED STATES PATENT OFFICE.

' CHARLES M. BAKER, OF KANSAS CITY, I'IISSOURI.

1 manna ISM. T pac'r paw 1v T allwhom it may concern: I a Be it known that I, Cnannns Banna, a citizen of theUnited States, re iding at Kansas City, in the county of Jaclrfin and 5 State of Missouri, have invented certain new and useful Improvements in Traction Mechanisms,'of,which the following is a full',j

clear and exact description, such as will enab eothers skilled in the art to which it appertains to make and use the same.

The invention relates to traction mechanism for propelling agricultural imple angle of the wheels and applying the power iso that the machine will travelin a circle, this requires a circuit at each end of. the 26 field, or moving the machine forward and backward alternately, changing the angle of the wheels for each movement until the machine is turned to the desired position. These movements at each end and often at 80 each corner of the field require a certain amount of ground that cannot be cultivated, resulting in the loss to cultivation (if valuable land, and usually a portion of the land that is cultivated becomes. so compacted by 85 the wheels of the machine that it is worthless for producing purposes.

It is essential that traction mechanism for agricultural purposes be so constructed that a forward or backward movement of 40 the machine will not be required to turn the machine toany angle or completely around end for'end, so that plows or harvesters may be run to the end of the field and turned as on a pivot to the position for the return trip, or to a right angle position in the case of turning a corner, to avoid thewaste of land as heretofore.

an improved traction mechanism that may be detachably attached to the ordinary imtached to a on tivator plow. The present invention seeks to provide- Speciflcation of Let ters latent. Patented Feb, 20, 1917, Application and rul is, 1914. swarm. a: 1,118..

machine in any horizontal direction the machine may is turned completely around without changing the positlonof one of the. wheels of the opposite end of the ma'-' .chine, which enables the operalor in plowing to run the plowsto the end of the field and turn arouad without makinga circuit, placing the plows facing the opposite direction and imme iiately along side of the strip of land just completed 'or plowed.

The tractor vheel of the present invention may be turner. to an angle that will pivot the machine :11 any desired point of the opposite end so that the return trip may be started in the same place, or immediately along side,or in any desired place, which is very advantageous in propelling plows,

harvesters and the like.

A further object of the inventionisto reduce the friition, the elimination of differential gears and general simplicity being large factors in this direction.

,A still further object of the invention is to reduce the cost of the mechanism so that duce the cost of agricultural work, but also reduce. the cc st of the equipment of the ordinary farm, the elimination of difi'erential gears am. general simplicity of construction bemg large factors in thlsdlrec tion. i

With thesennd other objects in view, the lnVBIll310l'1 C0n1 nets in the features 'of con- 'struction, conhinations and. arrangements Figure 1 is I, view in elevation of the improved tracticn mechanism with a portion broken away t) show the coi'istruction of the interior.

80 it may suppla it the horse and not only rc- I the same l ne as Fig. 6, but showing a slightly different arrangement of the gearlng. 1

F ig. 8 is a view in, elevation of the mechanism attached to and forming part of the usual traction engine.

Fig. 9 is a plan view of the'niechanism attached. to and forming part of the usual traction engine.

The traction wheel 1 is journaled on shaft '2 and provided with sprocket wheel 3 which is secured to the. hub 4 of the wheel, the shaft extending either side of the wheel and 'through the yoke 5 and being secured therein by nuts 6. i 1

The yoke 5 is provided with the horizontally disposed circular ball track 7 which is a companion to the ball track 8 of the drum 9, the balls 10 forming a bearing by which thedrum and connections are supported by the yoke, the balls forming a hearing in all horizontal directions as well as vertically. The yoke extends upward within the drum 9 and is providedwith bearings 11 to receive the shaft 12, the upper end 13 of the yoke being journaled in the drum 9; v

Securedsto the shaft" 12 is sprocket wheel 14 fronr which the chain 15 drives the sprocket 3 and wheel 1, the shaft also having secured thereto ,thebevel gear 16, the latter meshing withgear 17 shown integral with gear 18 and journaled on the bearing 19 of the yoke 5.

The drum 9 is provided with thebearing box 20 in which is journaled the shaft 21, the end of the shaft protruding within the drum and having rigidly mounted thereon the pinion 22 which meshes in gear 18.

It will be understood from the foregoing that if shaft 21. be rotated the Wheel 1 will rotate no matter at what angle it may stand with reference'to the position of shaft 21.

The shaft 21 is jonnnaled in box 23 and has rigidly mounted thereon the bevel gear 24 into which mesh the clutch bevel gears, 25 and 26, the clutch gears being loosely V mounted on the shaft 27 and engaged and.

disengaged by clutches 28 and 29 respectively, the clutches being operated by bellcrank lever 30, bar 31, and handle bar'32.

The shaft 27 is driven by sprocket Wheel 33, chain 34, and sprocket wheel 35, the latter being rigidly mounted on the shaft 36 of the engine 37.

It is obvious that ifclutch 28 be engaged shaft 21 will be revolved in one direction while if clutch 29 be engaged shaft 21' will rotate in the opposite direction, therefore no matter which way shaft 36 of the engine 37 is rotated shaft 21 may be operated in either direction and'the wheel 1 turned in either direction at will. v

Extending outward from ball track 7 and as shown integral therewith is sprocket clutches being operated by levers 46, 47 and 48, and reach rod 49.

The clutch coupling 60 is provided in shaft 21 and operated bylever 51 and reach rod 52 for the purpose of disconnecting the driving mechanism from wheel when it is desired to revolve wheel'l in a horizontal direction and not rotate-the wheel in the direction of its circumference.

From the foregoing it will be understood that the wheel 1 may be revolved horizontally in either direction without being ,rotated circumferentially, the advantage being that when the end of a field is reached the rotation of the wheel may be stopped and the wheel revolved horizontally to slightly beyond a right angle tothe line of travel, after which the wheel may be rotated in the direction of its circumference and the machine turned end for end without longitudinal movement, placing the machine immediately along side of where the last trip was finished. .It is obvious that the angle of wheel 1 may be so regulated as to turn the machine so that the longitudinal center thereof will be in the same line as that occupied before turning, or that the wheel may be so setas to move the machine to one side while turning, and the side movement may be so re ulated as to accommodate the width worked y the machine. Y

The frames 53 extend from the drum 9 and support the engine 37 and intermediate parts,- the frames being connected to the axle 54 by bolts 55, the axle being supported by wheels 56 journaled thereon, and the plows 57 being connected to the frame by hangers 58 and bolts 59. p

In Fig. 4 the mechanism is shown coned to a wagon, the purpose of the views being to show that the mechanism may be ofuniversal useoin the propelling and working of implements such as are used in agricultural pursuits.

nected to a harvester, and in Fig. 5 connect-- In Figs 8 and 9 the mechanism is shown connected to the usual form of traction engine in which connection the wheel 1 ,may

be used to assistin progelling and for turn- 7 ing, or only for turnin tion enginebeing of well known and usual construction is not further described.

Having described my invention, what I claim. and desire to secure by Letters Patent i's: f q 1. In traction mechanism, ai frame, a. housing secured to and as desired, the tracftame, a journal bearing in said housing, a
